Solving Projectile Motion Homework: Displacement, Velocity, and Equations

[Buzur]

Homework Statement

I have been given the Horizontal Displacement (Distance), Vertical Displacement (height), and Time (secs). How would I find total displacement? Velocity? Average Horizontal Velocity? Average Vertical Velocity?

Homework Equations

Um something with cosine and sine?

The Attempt at a Solution

And I honestly lost in all this. I don't even know where to start.

And I honestly lost in all this. I don't even know where to start.

Honesty is a good thing. Read up here for a start on vector addition using pythagorus for displacement calculations, then please show an attempt.
